Hi, >+1 > >I'm in complete agreement with John here. Adding the MUST requirement for >GRUU's on the SSP is in my judgment setting the bar too high. The evidence >is here. > >https://www.sipit.net/SIPit26_Summary > >Its not clear to me what are the percentages of client vs server in the >SIPit results but I'm aware that many of the vendors of proxy's in current >SSP deployment do not currently support GRUU's. I assume the support for GIN was more or less zero. So, rather at looking at the current support of GRUU, I think the question is: IF you are going to implement support for GIN, are you also willing to implement support for GRUU? >I prefer the use of SHOULD here. As part of the War On Shoulds: if you are going to use a SHOULD, you need to describe when it doesn't apply. Regards, Christer -----Original Message----- From: martini-bounces@ietf.org [mailto:martini-bounces@ietf.org] On Behalf Of Elwell, John Sent: Thursday, September 02, 2010 1:04 PM To: martini@ietf.org Subject: Re: [martini] Consensus call: Resolution of Ticket #57 I think what is paramount here is the ability for gin to gain traction in the market place. Although in Maastricht I agreed to this resolution, along with the other people in the room at the time, I had earlier in the meeting expressed a concern about raising the bar too high for SSPs to adopt gin. If SSPs are happy to keep support for public GRUU as a MUST, that is fine with me. But if SSPs say this raises the bar too high and they will not be able to implement gin within a reasonable timescale, I am concerned. I know GRUU is needed to support attended transfer using REFER/Replaces. It is also required to support transfer using REFER on a new dialog. However, transfer between domains is generally done by 3PCC means (re-INVITE), because of security / charging concerns about acting on a REFER request from another domain. In my opinion public GRUU is not a necessary component of a basic, entry level SIP interface between SIP-PBX and SSP.
